Inclining and rotating table apparatus

Abstract

An inclining and rotating table apparatus is provided with a rotary table device having a driven rotating shaft driven to rotate by a first drive source, and a rotary table driven to rotate by the driven rotating shaft; a driven turning shaft for causing inclination of a table surface of the rotary table device by causing the rotary table device to turn, the driven turning shaft being driven to turn by a second drive source; and a clamping device for clamping at least one of the driven rotating shaft and the driven turning shaft.

What is claimed is: 
     
       1. An inclining and rotating table apparatus comprising:
 a base; 
 a rotary table device supported by said base, the rotary table device having
 a driven rotating shaft driven to rotate by a first drive source, 
 a rotary table, and 
 a rotating turret that is connected to said rotary table and is rotated by said driven rotating shaft; and 
 an oscillating turret; 
 
 a driven turning shaft on said base for causing inclination of a table surface of said rotary table device by causing said oscillating turret to turn, said driven turning shaft being driven to turn by a second drive source; and 
 a clamping device for clamping at least one of said driven rotating shaft and said driven turning shaft; 
 wherein said clamping device has a thin-walled sleeve arranged such that a gap is provided along a circumferential direction of at least one of said driven rotating shaft and said driven turning shaft; 
 said clamping device clamps said at least one of said driven rotating shaft and said driven turning shaft by deforming said thin-walled sleeve towards said at least one of said driven rotating shaft and said driven turning shaft; 
 said gap includes an oil; and 
 a surface of said at least one of said driven rotating shaft and said driven turning shaft is provided with a groove into which said oil flows when said clamping device clamps said at least one of said driven rotating shaft and said driven turning shaft by deforming said thin-walled sleeve towards said at least one of said driven rotating shaft and said driven turning shaft. 
 
     
     
       2. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said thin-walled sleeve has a thickness of 5 mm or less. 
 
     
     
       3. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said clamping device is provided for clamping both said driven rotating shaft and said driven turning shaft. 
 
     
     
       4. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said driven rotating shaft and said driven turning shaft each has a cam; 
 wherein said rotary table and said rotary table device each has a cam follower; and 
 wherein, using said cam and said cam follower, said rotary table is driven to rotate by said driven rotating shaft, and said rotary table device is driven to turn by said driven turning shaft. 
 
     
     
       5. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said inclining and rotating table apparatus has neither
 a dwelling period in which said rotary table does not rotate even though said driven rotating shaft is driven and rotating, nor 
 a dwelling period in which said rotary table device does not turn even though said driven turning shaft is driven and turning. 
 
 
     
     
       6. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said clamping device clamps said at least one of said driven rotating shaft and said driven turning shaft by deforming said thin-walled sleeve such that said thin-walled sleeve adapts to the shape of a circumferential surface of said at least one of said driven rotating shaft and said driven turning shaft. 
 
     
     
       7. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said thin-walled sleeve is positioned on an outer side in a radial direction of said at least one of said driven rotating shaft and said driven turning shaft; and 
 wherein said clamping device clamps said at least one of said driven rotating shaft and said driven turning shaft by deforming said thin-walled sleeve from said outer side in the radial direction towards said at least one of said driven rotating shaft and said driven turning shaft. 
 
     
     
       8. An inclining and rotating table apparatus according to  claim 7 ,
 wherein said clamping device further comprises a fluid containing section for containing a fluid, said fluid containing section being arranged on said outer side in the radial direction with respect to said thin-walled sleeve; and 
 wherein said clamping device deforms said thin-walled sleeve by a pressure of the fluid that is filled into said fluid containing section. 
 
     
     
       9. An inclining and rotating table apparatus according to  claim 8 ,
 wherein said thin-walled sleeve is arranged only on an inner side in the radial direction of said at least one of said driven rotating shaft and said driven turning shaft with respect to said fluid containing section. 
 
     
     
       10. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said driven rotating shaft has a roller gear cam; 
 wherein said rotary table has a cam follower; and 
 wherein, using said roller gear cam and said cam follower, said rotary table is driven to rotate by said driven rotating shaft without causing backlash. 
 
     
     
       11. An inclining and rotating table apparatus according to  claim 10 ,
 wherein said clamping device for clamping said shaft is provided on said driven rotating shaft. 
 
     
     
       12. An inclining and rotating table apparatus according to  claim 1 ,
 wherein said driven turning shaft has a roller gear cam; 
 wherein said rotary table device has a cam follower; and 
 wherein, using said roller gear cam and said cam follower, said rotary table device is driven to turn by said driven turning shaft without causing backlash. 
 
     
     
       13. An inclining and rotating table apparatus according to  claim 12 , wherein said clamping device for clamping said shaft is provided on said driven turning shaft.
